ArkPak Installed 9-14-2013
A few years back I bought the Goal Zero Ranger 350 Battery/Inverter kit and it worked out great.
Bought five of their three watt LED lanterns too that you can daisy chain off of each other where you just plug one light into the battery only.
This year the Goal Zero battery would no longer hold a charge.
As soon as you take it off of the charger, it would start to discharge, and it would be dead within a few days, not good.
I looked on Amazon to source a new one, and a lot of the reviews said the same thing, the batteries did not last very long.
I was reading in one of my Overland Journals about a new system out of Australia that was basically a nice battery box with charge ports built into it, 150 watt inverter, and you supply your own group 31 battery.
AGMs seem to be the favor since they do not spill, and I bought an Exide marine one listed in the links below after seeing that was the one ArkPak was using in their videos.
When the ArkPak was first introduced, it was for 240V overseas, but they started to produce 120V versions for us on this side of the world.
You can read up on all of the specs right here.

This was installed in my rig on top of the cargobox, and it can charge when it is in the vehicle by plugging in the optional 12V to 12V charger I bought, or from 110V at home, and you can if you want leave it hooked up at home all the time since it has a built in Smart Charger to keep from frying the battery.
With Goal Zeros products you do not need a charge controller since their batteries have one built in, but you do with the ArkPak if you are going to charge it up via your solar panel(s).
I went with the Goal Zero Guardian 12V Charge Controller since it will hook up to my Powerfilm 60W foldable solar panel, and the other end had large battery clips on it that you can hook to the ArkPak or even your own battery in your rig.
My rigs main battery is charged up by another charge controller I installed a few years back when using solar when camping to keep the battery topped off when using the ARB fridge/freezer for extended times when out camping.
Links For ArkPak
Both sites have some very cool videos to watch too of the ArkPak in action.

Exide XMC-31 MEGACYCLE AGM-200 Sealed Maintenance Free (AGM) Marine Battery from Amazon
Goal Zero Guardian 12V Charge Controller
Guardian 12V Charge Controller from Amazon (where I bought mine from)
Cable to mate a Powerfilm solar panel to the Goal Zero Guardian-12V Charge Controller from Expedition Off Road
I do not believe Goal Zero offers this cable, only Expedition Off Road where I bought mine from.
Here are some pictures from the installation in my FJ Cruiser earlier this morning.
All parts laid out showing the battery, ArkPak, 12V and 110V chargers, and the Guardian Charge Controller.
Installed on the brackets/mounting kit.
You can see the green LED on the 12V plug that powers the charger for it.
12V cable plugged into the charging port.
One bracket at each end of the box.
You loosen a screw on the mounting plates and slide its tongue into the bracket on the ArkPak, then retighten it.
Comparison of the Goal Zero Extreme Ranger 350 battery/inverter and the ArkPak.
One is considerably bigger, abut also way more powerful.
Three of Goal Zeros LED lamps hooked up to the ArkPak.
LED panel showing battery voltage and indicating a full charge.
The battery I received from Amazon last night was shipped from Exide this month, so it has not been sitting in a warehouse discharging for a long time.
Mock setup (notice the covered wingnuts on the ArkPaks external battery connections) showing how you would connect the Guardian Charge Controller to the ArkPak and to my Powerfilm 60 watt foldable solar panel.
This is a very well built unit, and I like that you can replace the battery should it ever go bad.
The whole package including the Exide battery and ArkPak is pushing over 80 lbs, I can feel it when I lift it
This will be great for running the LED lamps in camp, charging up batteries for my various electronics, and having a third backup battery.
